Yes I did - because think about one of our airline e-tickets. It is common that they feature a barcode for easy collection of data, instead of attendants having to type in numbers all day every day.
On the flip side, if you had one, or didn't - doesn't mean your e-ticket is any worse or better. It was a design/planning question, a barcode might influence the marker to consider if the overall design is worth an extra mark at most (remember, overall design - with or without barcode can earn you the same mark, it comes down to design!).
Hope everyone went well - don't stress about it!
